(sqrt18 + 2 sqrt3)^2

sqrt18  = sqrt9 * sqrt2  = 3 sqrt2

(3 sqrt2 + 2 sqrt3)(3 sqrt2 + 2 sqrt3)

=  9 *2  + 6sqrt6  + 6 sqrt6 + 4*3

= 30 + 12 sqrt6   answer

(_/18+2_/3)^(2

=(3_/2^(2 + (2)(2_/3)(3_/2) + 2_/3^(2)

=18+ 12_/6 +12

4) Arnold ate breakfast at a restaurant. His total came to $76.75. There is an 8% sales tax and 15% tip. What is Arnold's total
lisov135 [29]

Answer:

The total cost is $95.32.

Step-by-step explanation:

Given:

Total came to $76.75. There is an 8% sales tax and 15% tip.

Now, to find the total cost.

<em>8% sales tax is there so we calculate the amount after adding sales tax:</em>

$76.75 + 8% of $76.75

76.75+\frac{8}{100}\times 76.75

76.75+0.08\times 76.75

76.75+6.14

82.89

The cost after sales tax is $82.89.

Now, <em>the cost after 15% tip:</em>

$82.89 + 15% of $82.89

82.89+\frac{15}{100}\times 82.89

82.89+0.15\times 82.89

82.89+12.43

95.32

The cost after the tip is $95.32.

Therefore, the total cost is $95.32.

Andrews [41]

Answer:

d. 14

Step-by-step explanation:

  1. 3(2) = 3 × 2 = 6
  2. Plug 6 in: 12 + {10 ÷ [11 - 6]}
  3. 11 - 6 = 5
  4. Plug 5 in: 12 + {10 ÷ 5}
  5. 10 ÷ 5 = 2
  6. Plug 2 in: 12 + 2
  7. 12 + 2 = 14

The quotient of a number and -9 increased by 10 is 11.
andrezito [222]
So the division of a number and -9 or
x/-9

+10=11 or

(x/-9)+10=11
subtract 10 from both sides
x/-9=1
multiply both sides by -9
x=-9

Find lim x-&gt;2 for f(x)=
TiliK225 [7]

LHL in not equal to RHL , Therefore the limit does not exists , Option D is the answer.(none)

<h3>What is the limit of a function ?</h3>

The limit of a function at a certain point is the value that the function approaches as the argument of the function approaches the same point.

It is given that

lim x->2 for f(x)

\lim_{x \rightarrow 2^-}f(x) = \lim_{x\rightarrow 2^+}f(x)

f(x) = 2x+1 x ≤2

f(x)= x² , x >2

When both the function tends to 2

Left Hand Limit

f(x) = 2 *2 +1

f(x) = 5

Right Hand Limit

f(x) = x² ,

f(x) = 4

LHL in not equal to RHL , Therefore the limit does not exists.
